Potassium aluminum fluoride, also known as potassium aluminum fluoride or potassium cryolite, mainly exists in two forms: potassium hexafluoroaluminate and potassium tetrafluoroaluminate, and is often present in a mixture in industry.
Sodium fluoride (NaF) is an inorganic ionic compound that appears as white crystals or powder, odorless, hygroscopic, with a density of 2.78 g/cm 3, a melting point of 993 ℃, a boiling point of 1704 ℃, and is easily soluble in water (with a solubility of about 4.06 g/100 mL at 20 ℃). The aqueous solution is weakly alkaline, insoluble in ethanol, and can corrode glass. It is composed of sodium ions
Methyl fluorosilicone oil is a modified silicone oil with methyl end capping and side chains containing trifluoropropyl groups. Essentially, it is an oligomer of trifluoropropyl methylsiloxane. Due to its unique structure, it combines the advantages of siloxane and fluorocarbon compounds, and is widely used in multiple industries. The following is a brief introduction:
1、 Basic attributes Chemical structure: The molecular formula is C ? H ? Cl ? F ∝ Si, and the molecular structure contains trifluoromethyl (- CH ? CH ? CF ∝), methyl (- CH ∝), and two chlorine atoms (- Cl). The core is the silicon carbon bond skeleton of silane compounds, and the strong electronegativity of fluorine atoms gives it special chemical properties.
